The ionising radiation and gas-phase metallicity in the narrow-line regions of Seyfert galaxies

Thomas, Adam Douglas


The physical conditions in the narrow-line regions (NLRs) of active galactic nuclei (AGN) may be constrained by comparing spectroscopic observations with photoionisation models. The key parameters are the gas-phase abundances, the ionisation parameter, the gas pressure, and the shape of the ionising spectrum. The first part of this thesis presents a model of the ionising continuum radiation in Seyfert AGN. This model, OXAF, preserves the...[Show more]
